If I'm not mistaken. The formula for Potential Energy in Physics is

PE = mgy wherein PE = Potential Energy, m = mass, g = acceleration due to gravity, and y = height.

As you will be able to observe potential energy will be produced when the object has a height. Like a person on top of a building, a tennis ball in the air, etc.

What if the object has no height?

- Well, it's simple. When we let y = 0, and multiply it to g and m, PE = 0. Therefore there will be no potential energy produced.

If potential energy increases, then kinetic energy decreases. If potential energy decreases, then kinetic energy increases. This is because of the total mechanical energy, which is potential energy + kinetic energy. If one increases/decreases, then the other has to do the opposite in order to conserve the total mechanical energy.

Potential Energy can be measured in a variety of scenarios. For instance, the potential energy of an object increases with altitude, due to the gravitational force acting on the object and the height the object attains. As another example, a spring stores potential energy when it is stretched or compressed beyond its equilibrium position.

when it starts moving in the direction of the applied force. As soon as it starts moving it gains kinetic energy and loses potential energy (because it is moving towards the source of the force)

If it stays at constant altitude/ distance from the center of mass of the nearest large mass, no.

potential energy will not change always in cost of the kinetic energy ,i.e.velocity

Since kinetic energy is given by 1/2mv2, it depends on its mass and velocity,

So, Kinetic energy of a molecule will decrease if either the mass or velocity is decreased ..

Does mechanical energy of a coconut falling from a tree increases or decrease?

Kinetic energy increases whilst potential energy decreases. Total remains constant


How pressure changes as the velocity of a fluid increases?

If we assume that the fluid we are referring to is that of an ideal fluid (incompressible and non-viscous) and is undergoing a laminar flow, we can model this problem by Bernoulli's principle and equation. Bernoulli's principle states that if the above conditions are met, the energy density of a fluid must be a constant, fixed value. This means that if the velocity of a fluid increases, other factors must decrease for the energy density of a fluid must be conserved. Bernoulli's Equation is the sum of the magnitude of the pressure, kinetic energy and potential energy of a fluid is equal to a constant. Therefore, if a velocity of a fluid increases, the kinetic energy of the fluid increases. As a result, the pressure or the potential energy must decrease. Both or only one may change; the result is dependent on the situation.


When a ball is falling what is the energy change?

As a ball fall downwards, it's velocity continuously increases, therefore the kinetic energy increases. As the height from the ground level decreases, the potential energy decreases. Further, the total mechanical energy remains constant throughout the motion.


What is a good hypothesis for the question how will the stretch of the rubber band effect the potential energy created?

If the rubber band stretch increases, then the potential energy will increase. Or: If the rubber band stretch decreases, then the potential energy will decrease.


What will happen to the potential and kinetic energy as the ball falls?

How is kinetic energy affected by a change in velocity?

Kinetic energy increases with an increase in velocity and decreases with a decrease in velocity. KE = 1/2mv2, where m is mass in kg, and v is velocity in m/s.


What happens when kinetic energy is absorbed as an object moves toward the earth?

The kinetic energy increases as the velocity increases (KE = 1/2mv2) until terminal velocity is reached, at which point the velocity becomes constant, and kinetic energy will no longer increase. The potential energy and kinetic energy will be at equilibrium, where PE = -KE.


What happens when you decrease the velocity of a car?

as you decrease the velocity of a car, you decrease the kinetic energy.


How does velocity have an effect on kinetic energy?

The summation of potential and kinetic energy of an object is constant. When the potential energy of an object decreases the kinetic energy increases. Assume a falling stone from some high point above ground. At the beginning, the potential energy is maximum while the kinetic energy is minimum or zero. While the stone is falling, the kinetic energy increases while the potential energy increases (with the summation of both is constant). When the stone reaches the ground, the kinetic energy is maximum and the potential energy is zero.
